I meant aspect ratio.

MF4 wins again with its ability to auto-size thumbnail images to a
consistent aspect ratio. No matter what the aspect ratio of my clip,
the thumbnail images all look the same in terms of their aspect ratio,
I have worked around this in TDA by using a wide frame for the
thumbnails, which masks off the larger image and makes all of them
look the same. However in one instance the frame covered up a small
part of the text on the thunbail. I can remake the clip to take that
into account.
